Explore how blood first came through the fall and became part of human nature, carrying corruption and defilement. “Flesh and blood cannot inherit the kingdom of God” (1 Corinthians 15:50), showing that blood is temporary and cannot enter the immortal state God has prepared. Yet, God allowed blood to serve a purpose in His redemptive plan — Jesus’ blood atones for the soul — while the prophets looked forward to a time when God would “cleanse their blood that [He] has not cleansed” (Joel 3:21). This points to a future hope when the fallen nature is washed away and blood itself is removed, preparing the body to receive immortality and the fulness of God.
